- Jekyll has now returned and claims that his relationship with Hyde has ended.
- He tells Utterson that the police won't find him and shows him a letter from Hyde.
- When Utterson questions Jekyll if he has been threatened, Jekyll replies in the affirmative.
- On the way out, Utterson asks the butler how the letter from Hyde arrived.
- When the butler tells him that there were no letters in the usual mail, Utterson find something suspicious.
- Finally, Utterson discovers through Mr.Guest that Jekyll and Hyde have extremely similar handwriting.

The most significant revelation is the fact that Jekyll and Hyde have similar handwriting and that they may be the same person. This is the most significant event because this solves the alibi behind Hyde's crimes and strange disappearances. Utterson actually gets close to forming an answer to this mystery.
